电子产品一直是全自动点胶机商家的主要输出范围,全自动点胶机商家想要抢占电子产品的市场,应牢记的就是根据当下需求来进行生产经营。
Electronic products have always been the main output range of automatic dispensers. In order to seize the market of electronic products, automatic dispensers should bear in mind that production and operation should be carried out according to the current demand.
影响点胶效果的要素通常有点胶量的大小,点胶压力,针头大小 ,针头与工作面之间的间隔,胶水的粘度,胶水温度,固化温度曲线,胶水中气泡,需求特殊设定的流体等等,下面昌盛人员就来为大家做一个简单的介绍,希望可以有所协助。
The factors that affect the dispensing effect usually include the size of dispensing amount, dispensing pressure, needle size, distance between the needle and the working face, glue viscosity, glue temperature, curing temperature curve, bubbles in glue, and fluid required for special setting, etc. below, Changsheng personnel will make a brief introduction for you, hoping to help.
点胶量的大小通常以为胶点直径的大小应为产品间距的一半,这样就能够保证有充足的胶水来粘结组件又防止胶水过多。点胶量几由时间长短来决议,实践中应依据温度和胶水的特性选择点胶时间。


First of all, the size of the dispensing amount usually assumes that the size of the glue dot diameter should be half of the product spacing, so as to ensure that there is enough glue to bond the components and prevent excessive glue. In practice, the dispensing time should be selected according to the temperature and the characteristics of the glue.
其次点胶压力方面,通常压力太大易形成胶水溢出、胶量过多;压力太小则会呈现点胶断续现象和漏点,从而招致产品缺陷,所以需求依据环境温度和胶水粘度等要素停止调理自动点胶机。
Secondly, in terms of dispensing pressure, too much glue is easy to form when the pressure is too high; if the pressure is too small, it will lead to intermittent dispensing and leakage, which will lead to product defects. Therefore, it is necessary to stop conditioning the automatic dispenser according to the environmental temperature and glue viscosity.
再者,点胶机针头通常要选取针头内径大小为点胶胶点直径的1/2左右的针头,点胶过程中,应依据产品大小来选取点胶针头。
In addition, the pinhead of dispensing machine usually needs to select the needle whose inner diameter is about 1 / 2 of the dispensing point diameter. During dispensing, the dispensing needle should be selected according to the product size.
还有,针头与工作面之间的间隔,不同的点胶机采用不同的针头,有些针头有一定的止动度,因而需求把握好点胶间隔,以每次工作开端之前应做针头与工作面间隔的校准,即Z轴高度校准。
In addition, the distance between the needle and the working face is different. Different dispensers use different needles, and some needles have a certain degree of stop. Therefore, it is necessary to grasp the dispensing interval and calibrate the spacing between the needle and the working face before the beginning of each work, i.e. z-axis height calibration.
除却全自动点胶机自身的要素,胶水的粘度直接影响点胶的质量,粘度大,则胶点会变小,以拉丝;粘度小,胶点会变大,进而可能渗染产品,而胶水温度应为23℃~25℃;环境温度对胶水的粘度影响,温度降低粘度增大,出胶流量相应变小,更容易呈现拉丝现象。胶水固化温度曲线消费厂家已给出,在实践应尽可能采用较高温度来固化,使胶水固化后有足够强度。
In addition to the elements of the automatic dispenser itself, the viscosity of the glue directly affects the quality of the dispensing. If the viscosity is high, the glue point will become smaller and even wire drawing will occur; if the viscosity is small, the glue point will become larger, and then the product may be dyed, and the glue temperature should be 23 ℃ - 25 ℃; the environmental temperature will affect the viscosity of the glue, the temperature will decrease, the viscosity will increase, and the glue flow will be reduced accordingly, which will make the drawing phenomenon easier 。 The curing temperature curve of glue has been given by the consumer. In practice, it should be cured at a higher temperature as much as possible, so that the glue has enough strength after curing.
另外胶水一定不能有气泡。一个小小气泡就会形成许多产品没有胶水;每次中途改换胶管时应排空衔接处的空气,避免呈现空打现象。
In addition, the glue must not have bubbles. A small bubble will form a lot of products without glue. When changing the rubber tube midway, the air at the joint should be emptied to avoid empty hitting.
电子产品越来越重视用户体验,轻薄化就是其中一个主要的发展趋向。招致电子元件越来越小,元件的大小在1mm左右曾经很常见。在电路板上的元件之间的间隔也越来越近。传统点胶机用肉眼人工示教编程的方式曾经无法精确定位了,应用CCD成像技术,将产品放大30-50倍显现在电脑屏幕上,停止精确定位编程才干满足客户的消费请求。
Electronic products pay more and more attention to user experience, and lightness is one of the main development trends. As a result, electronic components are becoming smaller and smaller, and the size of the components is about 1 mm. The spacing between the components on the circuit board is getting closer and closer. Traditional dispensing machine with naked eye manual teaching programming method has been unable to accurately locate, the application of CCD imaging technology, the product magnified 30-50 times displayed on the computer screen, stop accurate positioning programming ability to meet customer demand.
应用不同像素的CCD和镜头不同放大倍数,以及多种光源的组合,能够完成十分准确的定位精度,同时能够经过编程顺应产品本身的个体误差。
The application of CCD with different pixels and different magnification of lens, as well as the combination of various light sources, can achieve very accurate positioning accuracy, at the same time, it can be programmed to adapt to the individual error of the product itself.
响点胶精度的因素很多,自然不止上面所举的一些,有的时候甚是各种力量共同作用的结果。这就对点胶工艺提出了更高的要求,一方面应当尽量避免问题的出现,另一方面,问题已经出现的时候需要根据实际生产操作流程找到原因,问题。
There are many factors affecting the accuracy of dispensing. Naturally, it is not only some of the above mentioned, but sometimes even the result of the joint action of various forces. This puts forward higher requirements for dispensing process. On the one hand, problems should be avoided as far as possible. On the other hand, when problems have appeared, the causes should be found and solved according to the actual production process.
